This book was released on 2015 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Short-horned lizards (Phrynosoma douglasii species complex) occur throughout the inter-montane West and Great Plains of western North America. The comparative morphology and color pattern variation of short-horned lizards was studied in 3,174 specimens. Multivariate analyses of 20 morphological and color-pattern characters were applied to 977 specimens, and univariate statistics were summarized for 52 samples totaling 1,134 specimens. The results of the morphological data analyses support the recognition of P. douglasii (Bell 1828) as a distinct species, and the resurrection of P. brevirostris Girard 1858a and P. ornatissimum Girard 1858a as species distinct from P. hernandesi Girard 1858a. Two new species allied to P. brevirostris are described: P. bauri sp. nov. from the eastern plains of Colorado and northeastern New Mexico, southeastern Wyoming and southwestern Nebraska south of the North Platte River, and P. diminutum sp. nov. endemic to the San Luis Valley of southern Colorado and northern New Mexico. The Mexican taxon brachycercum Smith 1942 is reassigned as a subspecies of P. ornatissimum, based on non-discrete character differences and overall morphometric similarity. The ranges of P. hernandesi and P. ornatissimum broadly overlap in central New Mexico, the former taxon occupying the coniferous forests of disjunct mountain ranges, the latter occuring in the surrounding desert grasslands. Principal components analysis has revealed morphological evidence of hybridization where the two taxa meet, generally within ecotones between montane forest associations and grasslands. Principal components analysis has also revealed a high level of morphological variability in populations occurring in the Colorado Plateau region of northeastern Arizona, northwestern New Mexico, extreme southwestern Colorado and adjacent Utah. The evidence suggests that these populations arose through past hybridization between the two species. The taxon ornatum Girard 1858b, although sharing several traits with P. brevirostris, is morphologically close to P. hernandesi. It is regarded as a stabilized population of hybrid origin, but treated taxonomically as a subspecies of P. hernandesi. The taxonomic arrangement in this study, with the exception of P. douglasii, is largely discordant with the proposed taxonomy from a previously published study based on mitochondrial DNA sequence data.

Download or read book Herpetological Osteopathology written by Bruce M. Rothschild and published by Springer Science & Business Media. This book was released on 2012-01-05 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: As scientific analysis of testable hypotheses has replaced the speculative approach to study of bone disease in recent and fossil amphibians and reptiles, the field has advanced from simply reporting observations to analyzing their implications. This process is predicated upon a reproducible data base which explains/diagnoses the nature of bony alterations and a secure review of the literature. Thereby hangs the rub. The herpetological literature are difficult to access (let alone read) and are scattered through many prominent and eclectic journals and in the lay literature. While older diagnoses often have not stood the test of time, the clarity of report descriptions usually allows confident identification of the underlying pathology.

Download or read book Introduction to Horned Lizards of North America written by Wade C. Sherbrooke and published by Univ of California Press. This book was released on 2003-05-08 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Horned 'toads' have long inspired curious humans, from ancient Indian rock artists and the earliest Spanish explorers to modern scientists. These lizards specialize on ants for food, employ distinctive defensive tactics for different enemies, arch their bodies to collect rainwater, and exhibit numerous other adaptations to arid environments. Wade Sherbrooke's wonderful book, packed with facts and personal insights, will give everyone from lay naturalists to seasoned field biologists a new appreciation for these magically bizarre animals."—Harry W. Greene, author of Snakes: The Evolution of Mystery in Nature "Written in language understandable by anyone, Sherbrooke's newly revised little book on horned lizards is an exceedingly useful reference that covers most of what is known about these interesting and unusual lizards."—Eric R. Pianka, author of The Lizard Man Speaks "Wade Sherbrooke has provided in this very readable book a concise introduction to the evolution and natural history of the horned lizards, their impact on human art, and their future in an increasingly human-dominated planet. No one has more first-hand knowledge of the life history of horned lizards than Dr. Sherbrooke, so this book represents more than a summary; Sherbrooke provides insight into the life and times of horned lizards as no one else could. Amateur and professional alike will find much to enjoy about this book."—Darrel Frost, American Museum of Natural History Praise for the first edition: "[This is] the horned lizard bible deluxe."—Coevolution

Download or read book Lizard Ecology written by Laurie J. Vitt and published by . This book was released on 2016-04-19 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a collection rich in implications for all fields of ecology, leading lizard ecologists demonstrate the utility of the phylogenetic approach in understanding the evolution of morphology, physiology, behavior, and life histories. Lizards, which are valued for their amenability to field experiments, have been the subject of reciprocal transplant experiments and of manipulations of resource availability, habitat structure, population density, and entire sections of food webs. Such experiments are rapidly rebuilding ecological theories as they apply to all organisms. As a demonstration of state-of-the-art historical and experimental research and as a call for philosophical engagement, this volume will join its predecessors--Lizard Ecology: A Symposium (Missouri, 1967) and Lizard Ecology: Studies of a Model Organism (Harvard, 1983)--in directing ecological research for years to come. Lizard Ecology contains essays on reproductive ecology (Arthur E. Dunham, Lin Schwarzkopf, Peter H. Niewiarowski, Karen Overall, and Barry Sinervo), behavioral ecology (A. Stanley Rand, William E. Cooper, Jr., Emülia P. Martins, Craig Guyer, and C. Michael Bull), evolutionary ecology (Raymond B. Huey, Jean Clobert et al., Donald B. Miles, and Theodore Garland, Jr.), and population and community ecology (Ted Case, Robin M. Andrews and S. Joseph Wright, Craig D. James, and Jonathan B. Losos). Originally published in 1994. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
